MACHINE FOR POLISHING WOODEN RODS ORV STICKS.

SPECIFICATION forming part of Letters Patent No. 357,028. dated February 1, 1887 Application filed May 12, 18H6. Serial No. 201,921. (No model.)

To all whom, it may concern.-

Beit known that I, HIRAM PLUMB,a citizen of the United States, residingin Philadelphia, Pennsylvania, have invented certain Improvements in- Machines for Polishing Wooden Rods or Sticks, of which the following is a specification.

My invention consists of certain improvements in. that class of machines for polishing round wooden rods or sticks in which the surface fibers of the rod orxstick are compressed and condensed by means of revolving presserrolls, the objects of my invention being to provide for the proper guidance. of the stick through the machine and its proper delivery therefrom, to readily regulate the amount of pressure imparted, tov adjust the machine for action upon sticks of different diameters, and to simplify the construction and facilitate 'the working of the machine.

In the accompanying drawings, Figure I is a side view, partly in section, of my improved rod or stick polishing machine; Fig. 2, alongtudinal section of the front end of the machine on the line 7 8, Fig. 6; Fig. 3, a transverse section on the line 1 2, Fig. 1; Fig. 4, a transverse section on the line 3 4, Fig. 1; Fig. 5, a transverse section on the line 5 6, Fig. 1;

and Fig. 6, an end view lookingV in t-he direction of the arrow, Fig. 1. A

A isa table or bench,to which is secured the base-plate a of a box, B, which contains three presser-rolls, D, D', and D, said rolls having long shafts d, d', and d2 extending rearward and adapted at their rear ends tov boxes e, carried by a standard, E, secured to the bench A, each of these shafts having a suitable beltpulley, f, by which it can be driven. The shafts have a peculiar relation to each otherthat is to say, each shaft where it passes through the box B occupies one of the angles of an equilateral triangle, the shafts where they pass through the boxes e having a like relation to each other, butthe angles of the rear triangle being out of line with those occupied by the shafts where they pass through the box B.

the shafts the peripheral surfaces ofthe presserrolls D, D', and D2 occupy such relation to each other that if a round wooden rod or stick In consequence of this disposal of is passed between the rolls the latter will serve not only to compress and condense the fibers on the surface of the stick, but will cause said stick to rotate rapidly, and at the same time will feed the stick forward through the box in the direction of the arrow. y

The presser-rolls have but a limited longitudinal bearing upon the stick; hence, in order to prevent any gyrating movement of the ends ot' the stick, I provide hooked guides F for receiving the stick as it issues from the box B, these guides serving to retain the end of the stick and insure the passage of the same through the box in a straight course.

The hooked guides are open at Vthe bottom, so that as soon as the stick has been freed from the influence of the rolls and passed beyond the limits of the box B it will roll from the guides into'abox or receptacle suitably located. Guides having simple circular openings, as shown, for instance, by dotted lines in Fig. 3, maybe used in place ofthe hooked guides when it is desired to discharge the stick at the end instead of at the side of the machine.

The shafts of the lower rolls, D and D2,

are adapted to fixed bearings; butin order to vary the amount of pressure imparted to the stick the shaft of the upper roll, D, passes through a slot, g, in the inner plate of the box B and has a bearing-block, t', adapted to a slot, h, in the outer plate of the same, so that said roll D is free to rise and fall, a weighted lever, J ,bearing upon the shaft d at a point adjacent to the box, so that by shifting the weight upon the said lever any desired degree of pressure may be imparted to the upper roll.

The bearing-block t' of the upper roll has a pin, m, which in the present instance is formed by a continuation of the shaft d. This pin is adapted to a notch in a pivoted arm, K, hung to the box B and having a slotted segment, a, to which is adapted a set-screw, p, whereby said arm may be secured in any desired position, and the limit of descent ofthe upper roll thereby restricted in accordance with the diameter of the stick or rod to be polished.

I claim as my invention- 1. The combination of the presser-rol1s,their inclined shafts, and bearings therefor, with guides which receive and direct the stick When IOO it issues from the rolls, all substantially as and a stop whereby the descent of the upper specified. shaft is arrested, said stop being adjustable 2. The combination of the presser-1olls,their vertically, all substantially as specified. inclined shafts, and bearings for the latter, In testimony whereofhave signed my name I5 5 with stick-guides hooked, as described, so as to this specification in the presence of two subto permit the lateral discharge of the stick, all scribing witnesses. substantially as specified.

3. The combination of the lower rolls having shafts with fixed bearings, the upper roll V'Vitnesses: IO having a shaft with movable bearing, a VVILLIAII F. DAVIS,

weighted lever acting upon said upper shaft, HARRY SMITH.
